Sam Lufti recently took the stand in his libel and battery lawsuits against Lynne and Jamie Spears to assert that despite Britney Spears' increasingly erratic behavior during his time with the pop star - which ultimately led to her 2008 breakdown and subsequent conservatorship - he was NOT giving her drugs!

And now, as the case continued yesterday, he's claiming that the behavior of Brit Brit's parents really hurt his feelings — and his chest!

According to Lufti's testimony, despite being thrown out repeatedly by security, Jamie kept showing up at his daughter's house attempting to physically assault him!

He explains:

"[Jamie] barged into the house, lunged at me with fists balled, and chased me around the kitchen island. He was spitting, shouting and angry, saying I'd better leave Britney alone or he'd beat the hell out of me. [The next morning] He came in, started yelling at me, accusing me that I was abusing his wife [Lynne], cornered me in the kitchen, punched me in the [chest] and threatened to kill me."

And Lynne, with her book, was no better, because her description of him as a "Svengali" resulted in a "huge spike in death threats, mainly from Britney's fans" leaving him "depressed, anxious and suicidal."

Well, isn't that such a shame?

Perhaps he might want to think about just how his control and manipulation over Britney's life was making HER feel!

Not to mention her PARENTS and loved ones, from whom he deliberately isolated her, no doubt resulting in their increased concern, agitation, and helplessness as they watched their daughter clearly in so much pain!

Just disgusting.

We sincerely hope that as this trial continues, the truth regarding his actions will clearly come to light, and Britney and her family can finally be rid of this man's relentless harassment of them.

Shane Redway -- a Canadian rapper and close friend of Drake's -- was killed early Saturday morning in a car crash. He was just 26 years old.

Redway and two others were killed when their car lost control, struck a guardrail and burst into flames. The crash occurred around 4am outside Pearson International Airport in Toronto. It's unclear who was behind the wheel. Police are investigating the crash.

Drake took to Instagram to remember Redway, posting two different tributes.
